No place else on earth combines a deep pure lake, so blue in color; sheer surrounding cliffs, almost 2,000 feet high; a picturesque island & a violent volcanic past. Unfortunately, one of the driest years in history has reduced water flow in streams and rivers across the Upper Klamath Basin, including Crater Lake and the surrounding region. 10 Place to see Before They're Gone.
